SPECIFICATION forming partof Letters Patent 1`\To. 519,263, dated May 1, 1894.

` Application iiled August 31, 1893. Serial No. 484,513. (No model.)

Z'o all whom t may concern.-

Be it known that I, ARTHUR J OsnPH LAR- KIN, a citizen of the United States, residing at Council Bluffs,in the county-of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Stump-Pullers 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a simple and eective device for pulling stumps from the ground whereby great power is obtained, the loosening of the stu mp and removing it from the earth is rendered simple and easily accomplished and the operation of the parts perfect in their action as well as possessing strength and durability'.

The invention consists in a device constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure l of the drawings represents a perspective view of my improved stump-puller in position for operation; Fig. 2 a detail sectional view of the operating parts thereof on an enlarged scale; `Fig. 3 an end view of the tension-screw with the wire located in the groove thereof, the wire being shown in section.

In the accompanying drawings A represents a suitable hand wheel which may have a plurality of hand-holds ot or any other preferred and well known means for turning the Wheel.`

This wheel which may be constructed in any desirable manner which is provided with a head B which in the present instance would be considered the hub of the wheel.

Instead of providing the head with a rim, spokes and hand-holds for turning it, any suit able means may be employed for turning the head in place of the wheel shown.

The head B may be formed with or provided with a screw threaded feeding sleeve C having at one end a circumferential flange b. This head and screw threaded feeding sleeve when formed separate are connected together by set-screws c, keys, or Otherwell known means so' that when the head is turned the sleeve will be carried with it. The interior screw threads of the sleeve C engage with exterior thereon to admit the tension screws D screw threads `upon a tension screw D, and when the head is turned it will cause the tension screw to feed or move forward in a direction toward the wheel. p

Upon the end of the tension sleeve C is a swivel coupling E and between the flange b ofv the sleeve and the ange of the coupling are ball-bearings d so as to decrease the friction and enable`` the sleeve to turn with the head more easily. The cOuplingE is provided with eye-plates e or other suitable means for attaching thereto a chain or rope g through the medium of suitable hooksfor other like fastenings, said chain or rope being secu red to y a tree, stump, or other suitable stationary object `within convenient position to the stump to be pulled. A flexible wire cable E is provided which has upon one end a knife-edged hook G with head 7c by which it can be driven into the stump to be pulled, or any suitable` hook or similar device may be substituted for that shown. The wire cable F has buttons h engaging with the wire between the buttons, a longitudinal groove c' being formed in the screws for that purpose. Any number of these tension screws may be used as found desirable, and whenthe device is in position shown in Fig. l with the Wire cable engaging with the stump to be pulled and the chain or rope engagingwith some stationary object, by turning the wheel A the tension-screws will be moved along through the medium of the screw threaded feeding sleeve engaging therewith, and carry with it the wire cable, as the buttons on the cable prevent the tension screw from slipping thereon or moving independently thereof. The grooves in the tensionscrews enable them to" be taken olf or re' placed at pleasure.

Havingnow fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a stump-pu1ler, a suitable Wirecable provided with means for connecting it to the stump to be pulled, one or more tension screws having longitudinal grooves for engaging with the cable, buttons or stops upon the cable, and means for moving forward the screws, substantially as and for the purpose described.

`2. A stumppuller consisting of a suitable cable provided with means for connecting it the tension screw is operated, substantially 1o with the stump to be pulled, one or more lonas and for the purpose set forth.

gitudinally grooved tension-screws engaging In testimony that I claim the above I have with the cable, buttons or stops upon the cahereunto subscribed my'name in the presence ble, a screw thread feeding-sleeve engaging of two witnesses.
